Abstract

This communication proffers a graphene based microstrip reconfigurable antenna capable of switching between two frequency bands (S-band 3.03 GHz and C-band 5.17 GHz and 6.13 GHz). A graphene nanoparticle based conductive ink is printed on the cotton showing surface resistance of 2.7 Sq. −1, conductivity of 0.37× 10⁵ Sm⁻¹. An excellent radiation efficiency of above 55% is achieved at the dominant mode (TM10, 3.03 GHz. The frequency reconfigurability is introduced by exciting the higher order modes, TM02 and TM20 through two different feeding locations and an external RF Switch.

基于石墨烯的多波段频率可重构天线

这种通信提供了一种基于石墨烯的微带可重构天线，能够在两个频段(s波段3.03 GHz和c波段5.17 GHz和6.13 GHz)之间切换。一种基于石墨烯纳米颗粒的导电油墨被印在棉花上，其表面电阻为2.7 Sq。−1，电导率为0.37× 105 Sm−1。在主导模式(TM10, 3.03 GHz)下实现了55%以上的优秀辐射效率。通过两个不同的馈电位置和一个外部射频开关激发高阶模式TM02和TM20，引入了频率可重构性。
